-LRB- CNN -RRB- -- He racked up two within the space of a month in 2008 , but six years on Padraig Harrington will once again find himself watching a major from afar .

The two-time British Open winner 's frustrating 2014 continued Monday after he failed to qualify for the U.S. Open for the first time in 15 years .

Harrington was unable to advance from the 36-hole qualifying event at Walton Heath 's New Course , falling six strokes short after recording rounds of 75 and 71 .

The disappointment follows on from the 42-year-old 's failure to qualify for the Masters for the first time in 14 years last month , with his five-year qualifying exemption from his 2008 U.S. PGA Championship win having expired .

`` The damage was done in the morning with that 75 , '' Harrington told the PGA Tour 's official website .

Harrington felt his unfamiliarity with the New Course played a part in his downfall .

'' -LSB- I -RSB- just made a few mistakes in not knowing the golf course and I was never comfortable with the pace of the greens , as there was a number of three-putts thrown in there , '' he added .

Harrington 's recent setbacks are all the more remarkable given that in 2008 he secured his second British Open title , before adding a maiden U.S.PGA Championship just a month later .

The Irishman 's form has suffered a dramatic decline in recent years and he is still searching for a first win on the European Tour or PGA Tour since claiming the U.S. PGA Championship .

Harrington , who revealed that he had undergone skin cancer treatment in February , has slipped to 214th in the world rankings .

The six-time Ryder Cup player is now set to take a week 's break before returning to the PGA Tour for the FedEx St. Jude Classic in Memphis , which takes place from June 5-8 .

Harrington 's compatriot Shane Lowry , meanwhile , built on his second-placed finish at the European PGA Championship Sunday to finish top at Walton Heath .

Lowry , who missed out to Rory McIlroy by a shot at Wentworth , carded rounds of 69 and 67 to secure his spot at the U.S. Open .

It is the second time in five attempts that the 26-year-old has been successful at Walton Heath in qualifying for the tournament .

`` It was really tough out there . I played okay and putted really , really well . I holed a lot of six to eight footers for par and carried a lot of momentum in from yesterday to get the job done , '' he told the European Tour 's official website .

`` I was three under this morning and this afternoon chipped in for eagle to get to five , so that got me going .

`` I just tried to play steady from there and not lose my head . It was tough last week and then 36 holes in this weather was very tough . I 'm looking forward to my bed tonight . ''

Meanwhile , two-time major winner Jose Maria Olazabal missed out on qualification after finishing alongside Harrington at two over .

The 114th U.S. Open takes place from June 12-15 at Pinehurst Resort and Country Club .
